if it would be that easy, everybody would do it
what do you mean by "good with computers"? do you know how to write code (C/C++)? are you yet experienced with running linux? have you ever compiled a kernel before? do you want to make a source-(AOSP)-rom (then you can get the source here: http://source.android.com/ and here: http://opensource.samsung.com/) or do you want to just theme and customize a stock firmware?
i think there are already some tutorials around which will help you in the beginning. just google for them!
i haven't done custom rom development myself but i would really like to get some (clean) aosp goodness on this phone. i am experienced with linux (use it since 6 years as primary os) and i can code c/c++/asm. so if you are in fact serious and able to go all the way. i would appreciate to help!

I'm pretty able to develop with Eclipse, so android sdk. Linux quite good, i prefer to use windows, but i know linux is necessary. First of all i'd like to know how to customize GALAXY fw and then i'll study how to compile a kernel, no one during my life helps me, and it's difficult for me because i'm not good with english and all tutorials are in english!
I'll try to work on it! Thank you

Can someone explain me how to cook a Galaxy S Froyo ROM with AOSP as the base and samsung drivers?

Could someone please explain to me how to flash the Korean firmware onto the European phone? Really need the native "record call" feature

I saw some instructions posted here
http://forum.androidcentral.com/hacking/40130-100-stock-captivate-rom-aosp-source.html

It's not difficult if you're comfortable with linux, shell scripts, custom kernels, and cross compiling.
Basically that's pretty much all it needs, Android systems are very similiar to a running linux system.
Boot off a bootloader (usually closed sourced) into kernel and initrd, then init loads the drivers, system and configs, after which is pretty much to your taste and likings.
Source code of android, samsung kernel source, are available online, google is your friend.

[REQ] Development Environment Setup for Moto G 2014

Hey there,
INTRO:
I'm a relatively new member to XDA and the Android Community as well. The Moto G (2014) is my first Android phone since ever. I was using iPhones (4,4S,5,5S), iPads and Mac and have Jailbroken and Developed Tweaks, Apps etc for iOS.
Now that I got my hands on this amazing device, I would love to contribute to the Community by developing and porting ROMs for the Moto G 2014.
WHAT? WHY?:
So if it isnt too much trouble could someone post a device-specific instructions, checklist and downloads to setup a development environment for Moto G (2014). I'm a pretty fast learner so any crude form of instructions would suffice. With the right heading and instructions I'm sure that I can contribute to this community.
PAST CONTRIBUTIONS:
If you're curious about what I've preciously done, just Google "Krishna Sagar iPhone" and you'll see. I've developed apps, Jailbreak tweaks and I've even been mentioned and credited by CNET.com for discovering the first solid evidence about 4G in the iPhone 5. (Before it was announced or released. Yea!! )
So any help at all is appreciated! You know.. Help Me to Help You!
Regards
Krishna Sagar

PS: I've searched XDA and found some tutorials but I'm looking for some device specific instructions and downloads such as Device Tree, Kernal, ROM sources etc.. and crude up-to-date instructions on how to setup a Build-Environment. Thanks

Reserved by OP:
Once I get a working set of instruction and successfully setup my Dev Environment, I will post concise step-by-step instructions on how I set it up so that others can use it as a reference.

Okay....i just learned these things past month.
So tell me where you reached so that i can guide you.

I am at the very beginning... From the start would be great. Like i said.. I dont want a lengthy tutorial.. I'll find the instructions myself
For eg: just say setup Android Kitchen instead of walking me through the installation setup.
I just need a crude checklist to begin. I've doing some searxhing of my own.. But like i said, i need a bit more devicr specific approach!

Device specific approach would start once you have downloaded the repo.
Till then.... Approach for all the devices would be same.
Que: You are talking about building the rom from source right??
Or you just want to modify the stock rom!?

Havent decided really.. Might start by porting ROMs initially.. then gradually work on my own ROM
Thanks btw for your help

And where can I download these device repos?

For Porting ROMs : Usually ports are done from working Cyanogen build or AOSP build, which we doesn't have yet. But, k2wl and shawn are main developers working towards that. Once we get those fully working then only you will be able to port another roms.
Regarding Device Repo: It's required to build rom from source, not for porting one.
repo is a "Source Code" file, which is approx 25-30 GB in size.

I see a pattern emerging - lack of guides

Hello! This will be a quick post about how it was good earlier and how it can be better today, so please, stay with me.
I've been using Sony's for a while now, starting with small and cute Sony Ericsson k510i, then k550i, then wt19i (LWW), and then Xperia SP. My "flashing career" started after I've lost warranty on my k510. At that time there wasn't a lot you can do to your phone - there were several official firmwares, various customization options, and a lot of custom patches. No competition, one latest official firmware, a big library of patches that you could port to your device, if someone didn't do it already. The only competing area were a lot of graphical patches, but you could compile them together on your phone. Like today, if you were doing something wrong with your phone - you'll get a brick and it's your fault. But for every device there was an instruction, a beautifully crafted instruction on what to do and how to do everything, step by step. Almost every thread included a complete set of links to get you started. If you needed to flash a customisation after installing something, there would be a link on how to flash custom right there.
Today I have my XSP and try to do something to it. So I open one link (non-sticky, needed to bookmark it), see a lot of ROMs, part of which are no longer maintained. Finally open one of them based on performance rating, and see that it needs some kernel. So I go to kernel list, and see that it can't be flashed without recovery. What recovery? One specific recovery, because another one can't flash it. Now how do I flash recovery in the first place? I need a manual for that. Now I go to kernel and ROM page and see that no manual is available for them, too. So I open main device page and don't see any manual, so I open a sticky thread. And guess what? I don't see manual there. And that's when I start a new thread, type my problem in, and see a non-sticky thread with last post made 2nd of May 2015, and no pages link to that thread at all.
Is that how it goes this days? A newbie comes in, spends whole evening, opens 10 tabs, and still can't find anything relevant? I think we need to do something with this, revisit old threads, compile a new one-for-all guide, or at least a list of guides. And stick it, so people can actually see it. Otherwise there will be small closed community of those who already can develop and flash, and all the others who either got brick or is afraid to get a brick. Thanks.
---
UPD: And then I see that the kernel which I almost decided to flash is closed and all developers migrated to another one. I'm talking about tangerine and helium. Again, no info in the first post. And main developer openly says to users of his work - if it didn't work for you, don't use it. What's wrong with you people...

I'm deeply sorry if I offended somebody with my previous post. I'm happy that you guys do such amazing things with this 3 year phone. But damn, FULL INSTALLATION took about 10 minutes, counting PC reboot into linuxes to get fastboot working. In case someone struggles like me, use CyanogenMod instruction to get to Cyanogen Recovery; download TWRP Recovery, ROM of choice and GApps of choice; place all three ZIPs onto your sdcard; go to recovery, flash TWRP, reboot into TWRP (by pressing volume rockers while loading), do Wipe - Factory Wipe, flash ROM, flash GApps, reboot to normal. Wait for about 5 minutes (black screen is normal, there will be dots flying after a minute or so to keep you entertained).

Yes, It's that simple nowadays, so why bothering typing so much? I was in that situation with my SP, too, but if the are so many answers to these questions and so many threads... "You have to read" is the answer! A lot! It's for your own good, trust me. Now I can do anything I want with my phone with nohow! So a little reading and searching here and there is just positive experience for you. Don't complain, the people here ( well a part of them) are hardcore coders or themers or whatever. You can't just ask them to tell you all the stuff. If want help I'm always available.

Thank you for linking to my very dusty and lonely Flash ROM guide hahaha
No you didn't offend anyone at all. The guides are actually there, like how to use Flashtool, how to unlock bootloader, how to flash recovery and everything, it is just that they are buried deep with time as the development goes. The thread are there, in the General section and are awaiting to be searched. Though some are outdated, some are not and you can benefit from there.
Some searching will normally do, but if it didn't, just ask in the threads, someone will probably answer to you!
I always have my eyes on the General and Q&A subforums of the Xperia SP, and I will usually respond to a help-able problems. So if you have any problems, feel free to post in the Q&A subforum, and if not me, someone will help you. If there are nobody, don't feel offended. Maybe people don't know what to help or suggest (but lets just hope that is not what it will be )
About recovery, PhilZ and CWM is way outdated, and its time for everyone to make TWRP as a standard as it is a still updated recovery. Cyanogen Recovery in my opinion is crap as there are far too less feature plus, it enforce on signed flashable zips.
About the thread on Tangerine, the developer said dont use if it doesn't work is because of the norm of the Kernel. The kernel is made by using an AnyKernel template, hence render support for almost all Lollipop ROMs. Since ROMs can be updated and all ROMs have different sources, a simple change in the system part can render Tangerine unsupported, and the developer cannot do anything (definitely his choice, please respect that) to only fix the problem on one ROM which could possibly break support for the majority of the ROMs! This also appplies to Helium. Therefore, his words of "dont user it if it doesn't work" has a meaning, and it is not something to degrade new users and so.

Thanks for the answers and offering help, happily I was able to install my ROM of choice and it still works flawlessly, I was even able to squeeze 20 battery days from my old XSP.
Thinking about it, I start to understand why that dev answered like that. I was a python dev in the past and know how one feature can kill two others. Just in my head there is one current linux kernel, and all things that are developed should work with that particular kernel. Kernel comes before OS, if you will. Isn't it the case with ROMs and droid kernels?
About TWRP and reading: I honestly did read a lot of info before doing something, because it's my only phone these days. But it's so hard to find information on whether something is deprecated or not. As a new user, you wouldn't just google "is this deprecated and no longer used?", because that search will not provide any info. That is why during that evening and following morning I lost count of how many times I just shaked my head asking which recovery/kernel should I use and how do I install it? Latest being the easy one, because I already found TechnoSparks thread by that time.
In case anybody is interested, I installed Candy 5 on default kernel. But I still don't know if installing android 5 on a kernel used with android 4.2 was a good idea. It went well, however.

REQ rooted kernel 5.1.1 for Sm-t235 (source was published a month or two back)

sometime back this was posted
http://forum.xda-developers.com/showpost.php?p=63556533&postcount=135
unfortunately moonbutt closed his thread just when I and another member posted boot image etc on the board..understand he may have moved on to better things
not knowledgeable here but appreciate if someone can take this up or redirect this to some dev who can make a rooted kernel since the source has been published
thanks

SM-T237P
Would love to root my 5.1.1 tab , so I too would be begging for another developer to step in to fill this need. I need a kernel with UVC video support.

OKAY so now I know my posts were getting deleted when I asked for T235 kernel root

yesterday or may have been on Sat night, on the T533 thread I tried to catch moonbutt's attention by pointing to the T235 source (when apparently he was saying the T533 had no source but was addressing that kernel) and now that post has gone like on his closed thread (just when it seemed he was taking an interest thanking me for providing boot.img and other files)
anyway...need some dev who can volunteer to work on this and at least someone who would respond yes or no (deleting posts maybe to avoid a side conversation)
I pulled the source started to look it up and looked up on how to modify kernel..looked doable to a point but this is from a total novice (all i know is to mod some apk, compile/re-compile but no building stuff)

mac,
i had your post removed because it was interfering in H's thread. I tried with this device a little while ago but testers seem to think they are at liberty to not follow instruction, or just change their minds mid-stream like they haven't just wasted my time and resources. . The upside would be if you have the source and the setup to compile it and thereby test your own work then, i can absolutely run you through what you need to do, The tricky part is knowing which tools you need for the packing/unpacking of the ramdisk.
If this is a qcom/msm device you will need AIK which is the best solution.
If this is a marvell variant you will need ketut's degas bootimg toolkit which is the best solution.
You need [likely] to apply the patch mentioned in my thread to security/selinux/selinuxfs.c
Be aware that samsung's source releases are usually incredibly sloppy and the defconfigs for devices are usually somewhat off, missing config settings.
Check for sdcardfs xattrs, virtual xattrs, etc . you need to make sure those are selected in order for your internal and external storage to mount.
Find the correct defconfig for your device and post it as a zipped attachment. or check my thread and look at my sources on git, specifically the commit history [msm devices mostly] to get an idea of what you need. You can get a linux os running in a virtual machine and compile just fine as long as you have all the pre-requisites installed. The getting started link in my signature is a rough/general guide to help get you up and running.
m
ps, my thread is just locked, not closed, i was getting too many OT/non-dev postings. I open it when/if i have something new and then close it again.

thanks moonbutt74...totally understand...appreciate the links in your signature and other resources...will start looking into it (long long journey but gotta try)

mac,
no prob, recommended step 1, get your linux distro set up, stongly recoommend kali/debian 2.0, either in vm or better as 2nd os in a dual boot scenario.

SM-S820L Lollipop Update?

Is there any way to get Android Lollipop on the Galaxy Core Prime SM-S820L? I have read about custom ROM's but I still don't know much about them and can't find any for this model. If anyone has found or created a way to flash a custom ROM onto this device, please let me know.

I also own this device, and unfortunately there is very limited support in the custom Rom department. If there was to be a lollipop Rom, someone would either have to port one somehow, or build it from source. Given the development rate for this device, I don't predict it happening anytime soon, sorry to say.

not going to happen
i have been trying since february the answer i got from my carier was samsung is contracted not to support this device thats why that is so hard to find samsung told me to take the device to bestbuy to force update if they could probably irrelavent but maby it helps

SM-S820L Got the Shaft!
Yup! This seems to be the future for the SM-S820L, or lack of future I should say.
I too have the Samsung Galaxy Core Prime SM-S820L. I have spent lots of hours scouring the internet looking through every android related forum in hopes of eventually finding someone that is undertaking much needed programming to build a custom ROM for this CorePrime version.
If you are looking for a custom recovery to use. I can point you to my and others posts over at Needrom. The best I can offer is an unofficial TWRP release, but it DOES work! It does for myself at least and I am no Android Guru whatsoever.
I guess I am not allowed to post Links in any of my posts yet because I am still a NOOB on these forums. I'll PM you with some direction my friend!
I cannot take credit for coming up with any of that software. I simply rooted around long enough to compile a collection of tools and files that worked for me to modify the Recovery of my SM-S820L.
:good: Feel free to shoot me a Private Message on this site or to my personal Email....... [email protected]
I would love to help out as much as I can with modding your phone. Like I said, I'm not a proffesional but I have read up on the procedures used and been successful with my own Galaxy Core Prime:laugh:
